This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL32X550-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL32X550-U in place of this model. The MBL replacement upgrades to a riveted rolling-packed body and the current CMSG / DMSG / EMSG sensor switches (the MAL used CS1-M / DS1-M).
Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X550-U
The AirTAC Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X550-U is a double-acting aluminum-barrel mini round cylinder with a Ø32mm bore and 550mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL32X550-U, which matches its bore, stroke, force and mounting.

About the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X550-U
The AirTAC MAL32X550-U is a discontinued double-acting aluminum mini round cylinder featuring a 32mm bore and a 550mm stroke. Because 550mm exceeds the 500mm standard limit, this is a non-standard, made-to-order length. It delivers 402N of push force and 346N of pull force at 0.5 MPa, utilizing a G1/8 port and an M10x1.25 rod-end thread. The exact drop-in replacement is the MBL32X550-U, matching the bore, stroke, output force, port size, and flat-end mounting.
This legacy unit features a U flat-end back cover for rigid mounting and a fixed rubber bumper to soften end-of-stroke impacts. It lacks a magnet (-S), so it cannot accept a position sensor. The original MAL body uses threaded front and back covers, whereas the modern MBL replacement features a riveted rolling-packed body. Furthermore, if you ever upgrade to an -S MBL variant, you must switch from the old CS1-M/DS1-M sensors to the current CMSG/DMSG/EMSG switch family.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL32X550-U carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The MBL32X550-U produces the same force from the same bore — a true drop-in on output. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X550-U Is Used
PCB Edge Belt Routing
Drives a diverter gate on a SMT conveyor line, using the 402N push force at 0.5 MPa to deflect bare circuit boards into a downstream inspection lane within a tight machinery footprint.
Carton Flap Plow
Actuates a plow blade on a case erector to fold minor carton flaps, where the 346N pull force at 0.5 MPa retracts the mechanism cleanly before the sealing head advances.
Textile Guide Shifting
Shifts a fabric guide roll on a high-speed loom, leveraging the 550mm stroke to reposition the web material across the beam while maintaining a compact rear profile via the flat-end cover.
Replacing the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X550-U with MBL32X550-U
To replace the MAL32X550-U, order the MBL32X550-U. Confirm the 32mm bore, the 550mm non-standard stroke, the G1/8 port, and the PT thread form. The U flat-end back cover provides a rigid rear mount, which is highly recommended for this 550mm length because the 12mm carbon-steel rod has low side-load tolerance and is prone to bending without external guidance. If your application requires an adjustable air cushion instead of the standard fixed rubber bumper, step up to the MBLC32X550-U on the current line. A plain cylinder does not hold its load when air is lost; the rod will drift, so add an external rod lock or pilot-operated check valve if position holding is critical.
For sizing flexibility, you can step down to the 25mm bore (MBL25X550-U) which yields 245N push at 0.5 MPa if your load is lighter, or step up to the 40mm bore (MBL40X550-U) which provides 628N push at 0.5 MPa and a larger G1/4 port for higher flow if you need more force.
Upgrade checklist
- ✓ Order the MBL32X550-U (same bore/stroke/force)
- ✓ Same G1/8 port and mounting accessories
- ✓ Sensor: swap CS1-M/DS1-M → CMSG/DMSG/EMSG
- ✓ Need a cushion? use MBLC (adjustable air cushion)
- ✓ Confirm back cover (CA / U) and thread (PT/NPT/G)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.1 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Front/rear covers are threaded — not intended for field disassembly.
- check Use the correct mounting accessory (LB / FA / SDB) and back cover (CA / U / CM).
- check For new builds, specify the MBL32X550-U instead of this discontinued model.
Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X550-U FAQ
Yes, the MAL series is end-of-life. The exact drop-in replacement is the MBL32X550-U. It matches the 32mm bore, 550mm stroke, 402N push force at 0.5 MPa, G1/8 port, and flat-end mounting. The main physical change is that the MBL uses a riveted rolling-packed body instead of the MAL's threaded covers.
At 0.5 MPa it provides 402N push and 346N pull; at 0.7 MPa it provides 563N push, with a maximum theoretical force of 82 kgf at 1.0 MPa. Because this specific SKU lacks the -S magnet, it cannot accept a position sensor. If you switch to an MBL32X550-S replacement, you will need to use CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M series.
